BARIUM DEVICE This invention relates to machines for the examination of patients and more particularly to a barium device.

It is therefore the principal object of this invention to provide a barium device which provides for a control system of barium application, in combination with air contrast, if desired to be employed in the examination of patients.

Another object of this invention is to provide a barium of the type described, which employs lever means, piston means, hose means, valve means, and air control means so as to assure that barium enters the colon thereby renderring the patient ready for X-rays.

A further object of this invention is to provide a barium device of the type described, which will be superior to those of the prior art, in that, the present invention provides a control system of both the combination of barium and air.

Other objects of the invention are to provide a barium device which is simple in design, inexpensive to manufacture, rugged in construction easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawings, wherein:

FIG. 1 is a perspective view of the present invention.

FIG. 2 is a perspective view of the lever and wheel combination of the device which controls the operation of the two pistons shown in FIGS. 3 and 4 of the drawings.

FIG. 3 is a plan view of the piston contained unit of the device, shown in closed position.

FIG. 4 is similar to FIG. 3, but shows the unit in open position.

FIG. 5 is a perspective view of another piston contained unit of the device.

FIG. 6 is an exploded perspective view of the unit of the device which has air valve means and washer means for controling the barium and air flow.

According to this invention, a barium device 10 is shown to consist of a base 11 of which extending lever 12 controls the function of the device 10. Barium is kept in a reservoir 12a mounted on an IB stand (not shown) above device 10, the barium flowing by gravitational means downward. When device 10 is put into use, lever 12 is moved from the locked position L1 as shown on face 13 and is set to the letter B upon face 13. Barium is then allowed to flow through rubber surgical tube, identified as 14, through 15 and into the section labeled B of unit 16. The fluid continues to flow into surgical tube 17, into the patient, in order to assure that barium enters the colon, an air contrast system is employed. This is accomplished as follows:

Lever 12 is moved to position A upon face 13 of device 10, after which the barium flow ceases and air is introduced into the syste. Through means of surgical tube 17, air is pumped by means of squeeze bulb 18 attached to tube 19, the air being forced through section A of unit 16, and into tube 17 wherein it enters into the patient. Upon allowing the desired amount of barium to enter into the patient, the patient is ready to be X- rayed. At this point lever 12 is moved to a locked position 12 upon the face 13. Upon ecompletion of the X- raying, lever 12 is moved to the position D upon face 13, and lock lever 20 is moved to set position, so as to prevent further movement of lever 12. The lever 12 action at position D on'face 13 allows all of the barium to drain from the patient through units 16 and 21 I through tube 22, to a collection receptacle- (not shown). Upon completing the discharge of barium from the patient, lever 12 is unlocked and moved to the position W upon face 13. The above mentioned wash position allows the barium from the barium reservoir 12a to flow through the surgical tube '23 connected to units 15, 16 and 21 to the collection receptacle. In order to assure that a clear flow of barium results from the reservoir 12a, to the collection receptacle, the squeeze bulb 18 is pumped from time to time, the resulting action serving to essentially clean the device 10 and prepare it for another operation.

To further describe device 10 in detail, FIGS. 3 and 4 show the unit 15 (open and closed) respectively and FIG. 2 shows the lever 12 uncovered. As is shown in FIG. 2, lever 12 is secured fixedly to an isometric wheel 24 mounted on the colonic device 10, base 11, by means of a column support (not shown). This lever 12 by circular motion, controls the operation of two pistons 25 and 26 as shown in FIGS. 3 and 4 of the drawings. The pistons 25 and 26 in effect, apply direct pressure on the surgical tubing within which will contain air or barium. The function of unit 21 is such, that when lever 12 is at position B, on face 13, the piston 27 of this unit 21, compresses against the surgical tubing enclosed in the system so that the barium flows to the patient. When the lever 12 is moved to positions L1 and L2 and A, the unit 21 still remains closed. When lever 12 is moved to the position D (drain) and W (wash), piston 27 is released and allows fluid to flow out of device 10 and into the collection receptacle.

Referring to FIG. 6 of the drawing, the letter B indentifies the upper part of the unit where barium is allowed to flow when desired. The lower portion represents the air contrast aspect A. When the squeeze bulb 18 is employed to pump air into the patient, a rubber washer 28 and a nylon ball 29 with spring 30 means, prevents air from returning through the system. Washer 28 will prevent barium from backing into the air system.

It shall be noted that the wheel disc 24 secured fixedly to lever 12 has an inner disc attached that is flat in certain areas and recessed in others. When the control lever 12 is moved from one position to the next, the disc on the inner surface, in turn, controls the side movement of the pistons 25 and 26. The larger outer wheel 24 controls the movement of the piston 27 as shown in FIG. 5 of the drawings.

It shall be further be noted that the ends of the pistons 25 and 26 of FIGS. 3 and 4, are provided with a wheel bearing 25a and 26a respectively, the said bearings serving to reduce friction and will rotate when the control lever 12 is moved from one position to the other. The piston 27 of unit 21, includes a surface cap 21a.
